This study demonstrates considerable sensitivity response using different materials for an H-shaped surface plasmon resonance (SPR) sensor. The phenomenon provides selective sensitivity response with different organic materials. The structure consists of coupled metal along with an analyte. Analyte that employs the SPR effects which is sensitive to material changes with the surrounding refractive index. The optical properties of used metals are evaluated on the emerged permeability and permittivity ascertained by the combined Drude and Lorentz model. Varieties of some organic materials to control the SP are investigated. Annealing of gold, palladium, titanium, and silver thin films, the model is formed. These metals can monitor the sensitivity changes of the concentration on the surface of sensor. In this study, the range of wavelength is 320–620 nm with an achieved refractive index of 1.37–1.42. The evaluated sensitivity is maximum while for silver among various metals which is almost \(\sim\) 2.17 × 104 nm/RIU.
